Based on morphological computations, this study explores the productions of complex form from basic patterns during the process of time-based computations. By seeking simple rules from the domains of biology and design computation, and through recursive operations to derive complexities, the study uses the surface subdivision principle to discuss the morphological variations produced by computer generations. The latter part of the study further examines the decoration of designs of the digital era, using basic geometric transformation rules as the basis for iterative computations to produce complex and unpredictable patterns.

This study is divided into two parts. The first part attempts to explore the fundamental principles of morphogenesis. Initially using points and lines as the basis for discussion, rules such as those in path trajectory, gravitational field, cellular automata and intelligent behavior algorithms are then applied for morphogenesis. The second part uses surfaces and s as the computational factors and the principle of surface subdivision to conduct fractal processing on curved surfaces and volumes. By applying different conditions at each iterative step, slight variations in rules would cause significant differences in the final patterns generated. Finally, this study uses the column form as the basis for morphological computations, to explore the possibility of morphogenesis alterations via different applications and combinations of computational rules. This study categorizes the use of digital tools into two major groups: ISO-Surface and surface subdivision. While ISO-Surface is point-based and constructs surfaces through sequential arrangements of points, surface subdivision uses surfaces as the basic forms and achieves surface transformations by selecting and moving the control points.

Placement or replacement of different rules at each iterative computation is discussed in the study to produce irreversible results of morphological computations, and to derive possibilities with the same initial conditions but varying rules. Using such a conceptual design as the starting point, it anticipates to set new developments in the domain of architectural designs in the future, and to bridge the gap between virtual and practical applications of digital designs.
